c# - 无法重新膨胀 fragment 对话框 Xamarin 和 C#

Question

我的 fragment 对话框有问题。我有一个 ListView ，当我单击单个 ListView 项时，我可以进入 fragment 对话框。

但是当我回到持有 ListView 的父级并尝试重新进入 fragment 对话框时，我收到了这个错误。

Android.Views.InflateException:二进制 XML 文件第 1 行:扩展类 fragment 时出错

给我错误的行是

var view = inflater.Inflate(Resource.Layout.dialog_preview_busn, container, false);

这是XML文件

调用对话 fragment 的代码块。此代码位于 listview_ItemLongClick(object sender, AdapterView.ItemLongClickEventArgs e) 中。

Android.App.FragmentTransaction transaction_prev = FragmentManager.BeginTransaction().AddToBackStack(null);
        dialog_preview_busn previewBusn = new dialog_preview_busn(gName, gAddress, gZip, gNumber, gEmail, gWebsite, gHours, gImage);
        previewBusn.Show(transaction_prev, "Dialog Preview Business");

Answer 1

堆栈跟踪给出了以下错误:

Duplicate id 0x7f0a001d, tag null, or parent id 0x7f0a001c with another fragment for com.google.android.gms.maps.MapFragment

您可以在此处阅读有关此问题的更多信息:Duplicate ID, tag null, or parent id with another fragment for com.google.android.gms.maps.MapFragment

所以你可能想使用 replace()以确保您不会在 fragment 内膨胀 fragment 。确保在添加另一个 fragment 之前删除之前的 fragment 。

这里有一个注释:https://developer.android.com/about/versions/android-4.2.html#NestedFragments

Note: You cannot inflate a layout into a fragment when that layout includes a <fragment>. Nested fragments are only supported when added to a fragment dynamically.
